Hundreds of aliens flood the screen. Your weapons fire on their own. Your only job is to stay alive long enough to grow powerful enough to stop them.

Grimdark Survivors is a top-down roguelite horde survival game where you pick a hero, wade into waves of alien enemies, collect experience from kills, and choose upgrades that turn you from vulnerable to devastating — all within a single run that can end in seconds or stretch for twenty minutes depending on how well you move.

Play it free in your browser on PLRun with no download. Grimdark Survivors belongs to the horde survival genre popularized by Vampire Survivors, but it sets itself apart with a sci-fi alien invasion theme, a priority targeting system that lets you direct your fire, and a roster of heroes whose starting weapons and stats create genuinely different run experiences.

Your weapons attack automatically — the core skill is movement. You weave through gaps in the horde, collect XP gems dropped by kills, and choose from weapon and stat upgrades each time you level up. Every run builds toward surviving longer and reaching tougher boss encounters.

Developed by HITyara Games and built with HTML5, the game runs on desktop and mobile browsers as well as on Steam. The roguelite structure means each failed run still teaches you something — which weapon combos synergize, which upgrade paths scale, and which hero suits your positioning habits.
